Frequency Modulation   Creates complex spectral sidebands 
 
Frequency modulation creates spectral sidebands. A source signal, the carrier, is rate modulated (resampled) at a frequency determined by the modulator signal.
  Carrier input: The source to be modulated.

Modulator input: Signal that modulates the rate of the carrier. This gadget is only active if "Soundfile" is chosen as the modulation source.

Output file

Modulation source: Either an internally generated signal (sine, tri, saw, rect) or a user supplied sound file. Tri, saw, rect are not yet implemented.

Quality: FM is performed via resampling. See also the Resample module.

Modulation depth: The maximum resampling ratio. Refers to the input sampling rate.

Oscillator frequency: Frequency of internally generated sine, saw, tri and rect.


Toolbar: Popup menus for loading and saving settings, presets and options. Refer to a the basic chapter on process windows.

Processbar: Buttons for closing the module, starting and stopping processing. Process gauge. Refer to a the basic chapter on process windows.


Known bugs: Yes! Not yet working clean, produces artifacts

To be done: Internal signal generator.
